12 Putting the receiver into operation Mounting the receiver into a 19 rack Do not mount the stacking elements and do not fit the rubber feet when rack mounting the receiver. CAUTION! Risks when rack mounting the receiver! When installing the device in a closed or multi-rack assembly, please consider that, during operation, the ambient temperature, the mechanical loading and the electrical potentials will be different from those of devices which are not mounted into a rack. Make sure that the ambient temperature within the rack does not exceed the permissible temperature limit specified in the EM 100 G3 specifications. Ensure sufficient ventilation; if necessary, provide additional ventilation. Make sure that the mechanical loading of the rack is even. When connecting to the power supply, observe the information indicated on the type plate. Avoid circuit overloading. If necessary, provide overcurrent protection. When rack mounting, please note that intrinsically harmless leakage currents of the individual mains units may accumulate, thereby exceeding the allowable limit value. As a remedy, ground the rack via an additional ground connection. Rack mounting one receiver To mount the receiver into a rack, you require the GA 3 rack adapter (optional accessory): Secure the rack mount ears (supplied with the GA 3 rack adapter) to the receiver in the same way as described for the stacking elements (see page 8). Secure the blanking plate to one of the rack mount ears using two recessed head screws (M 6x10) (see left-hand diagram). Connect the antennas. There are two ways to connect the antennas: You can connect the rod antennas to the rear of the receiver (see page 9). In this case, insert the two blanking plugs into the holes of the blanking plate (see lefthand diagram). You can use the AM 2 antenna front mount kit (optional accessory) and mount the rod antennas to the front of the receiver (see right-hand diagram). When using more than one receiver, we recommend connecting remote antennas and, if necessary, using Sennheiser antenna accessories. For more information, visit the ew G3 product page at Slide the receiver with the mounted blanking plate into the 19 rack. Secure the rack mount ears and the blanking plate to the 19 rack. 10

When synchronizing a transmitter with a receiver, please observe the following: Improve the position of the antennas. If necessary, use antenna boosters. On your transmitter, adjust the audio level as high as possible without the level display for audio level showing full deflection (AF Max is at a level with the PEAK display). For more information, refer to the instruction manual of the transmitter. Only use a transmitter and a receiver from the same frequency range (see the type plate on the transmitter and the receiver). Make sure that the desired frequencies are listed in the enclosed frequency information sheet. Make sure that the desired frequencies are approved and legal in your country and, if necessary, apply for an operating license. Synchronizing a transmitter with the receiver individual operation Upon delivery, transmitter and receiver are synchronized with each other. However, if you cannot establish a transmission link between transmitter and receiver, you have to synchronize the channels of the devices: With the receiver, perform a frequency preset scan to scan the frequency banks for unused channels ( Scan New List, see page 17). 19

22 Adjustment tips Select a channel on your receiver ( Current List, see page 17). The receiving frequency of the channel must be approved and legal in your country (see above). Synchronize a transmitter with the receiver via the infra-red interface (see page 13). This establishes a transmission link between the transmitter and the receiver. Alternatively, you can set the channel on the transmitter manually: Make sure that you set the transmitter to the same frequency bank and the same channel as the receiver. For information on the setting options of the transmitter, refer to the instruction manual of the transmitter. Synchronizing transmitters with receivers multi-channel operation Switch off all transmitters of your system that are to be automatically configured. Channels used by switched-on transmitters are displayed as used. With one of the receivers, perform a frequency preset scan to scan the frequency banks for unused channels ( Scan New List, see page 17). Select a channel on this receiver ( Current List, see page 17). The receiving frequency of the channel must be approved and legal in your country (see above). Synchronize a transmitter with the receiver via the infra-red interface (see page 13). This establishes a transmission link between the transmitter and the receiver. Repeat for the remaining transmitter and receiver pairs as described above. Your multi-channel system is now set up. Alternatively, you can set the channel on the transmitter manually: Make sure that you set the transmitter to the same frequency bank and the same channel as the receiver. For information on the setting options of the transmitter, refer to the instruction manual of the transmitter. You can also freely select the receiving frequencies and store these frequencies in the frequency bank U. If you are using the frequency bank U, it might be that the receiving frequencies are not intermodulation-free: For possible frequency combinations, please refer to the frequency information sheet or calculate the frequencies (see below). If you want to use the frequency bank U : Make sure to use receivers of the same frequency range (see page 4 and the type plate of the receiver). Only use frequencies that are approved and legal in your country (see page 19). To ensure that the desired frequencies are intermodulation-free, proceed as follows: Calculate intermodulation-free frequencies using the Sennheiser Intermodulation and Frequency Management (SIFM) software (see Set each receiver to the same frequency bank. On one of the receivers, select a channel within this frequency bank (see page 18). 20

23 Cleaning the receiver Assign this channel one of the calculated receiving frequencies (see page 18). Synchronize a transmitter with the receiver (see page 13) OR Manually set the transmitter to the same frequency bank, channel and frequency that you set on the receiver.
